Just tried running this with a group.
Did some reading...everything keeps saying to break the healing stun she puts on you. To save some stamina and then break free.
I'm not the best player, but I must be missing something rather basic here.
I've got just under 37K (36,755) stamina, buffed. I understand "break free" to be the maneuver you do when you hit both mouse buttons at the same time.
But try as I might, no matter how many times I hammer the mouse buttons, nothing. I just cannot break the heal/stun. I can seem to do it well enough trash hits me with something, but just can't seem to break this one. I even tried one round against her by using just basic attacks with a bow, just to make absolutely sure I had enough stamina for a break. Nothing.
Is it this break free or the rolling one?
We spent a looooooong time fighting her, getting her to a whopping 93% until we finally just gave up.
I post because the last date I saw on this boss, in this forum was in February and referenced things such as using shards to regen stamina (which no longer works for everyone that way).
